A script co-written by Stanley Kubrick has been found by a British film academic who was researching the legendary director’s last picture, “Eyes Wide Shut.” The screenplay, “Burning Secret,” is an adaptation of a 1913 novella by Austrian novelist and playwright Stefan Zweig.

It was written by Kubrick and author and screenwriter Calder Willingham (“The Graduate”) in 1956. The story follows a mother and son on a holiday and a mysterious man who befriends the young boy in an attempt to seduce his mother.

It was known that Kubrick had worked on “Burning Secret” but not to what extent, or whether there was a completed screenplay. Nathan Abrams, a film professor at Bangor University in Wales, told BBC radio Monday that he was shown the 100-plus-page screenplay by the son of one of Kubrick’s collaborators, who wants to remain anonymous. The Guardian reported the find on Sunday.

“It’s a full script: beginning, middle, end,” Abrams told BBC radio. “As to whether that was the final one, we can’t say.”
